Following the reactivity inversion strategy, two different two-step sequences were designed and successfully applied to the asymmetric synthesis of spiro-bridged and spiro-fused heterocyclic compounds, which combined chromane, indole, and oxindole, three
Catalytic Enantioselective Decarboxylative Allylations of a Mixture of Allyl Carbonates and Allyl Esters: Total Synthesis of (-)- and (+)-Folicanthine

A highly enantioselective decarboxylative allylation of a mixture of enol carbonates and allyl esters has been achieved. The strategic viability of this methodology has been demonstrated through the total synthesis of cyclotryptamine alkaloids (-)- and (+)-folicanthine (1 a) and the formal total synthesis of (-)-chimonanthine (1 b), (+)-calycanthine (1 c), and (-)-ditryptophenaline (1 d).

experimental part, p. 5662 - 5665 (2010/11/18)
Reaction of cyclic diazoamides and cyclic olefins or heteroaromatic systems using copper(I) triflate as a catalyst furnished a variety of strained spiro-cyclopropanooxindoles in a diastereoselective manner under mild reaction conditions. The effect of copper(I) triflate and rhodium(II) acetate catalysts on the cyclopropanation was also studied.
First example of regiospecific intermolecular C-H insertion reactions of cyclic rhodium carbenoids: Novel synthesis of 3-indol-3′-yloxindoles

, p. 824 - 825 (2007/10/03)
Facile regiospecific intermolecular C-H insertion reactions of cyclic rhodium carbenoids have been achieved using diazo carbonyl compounds 1 and indole or N-substituted indoles to afford 1,3-dihydro-1′H-[3,3′]biindolyl-2-ones, 3a-o in an excellent yield.
